PET is also used in pre-clinical studies using animals.
PET is a valuable research tool to learn and enhance our knowledge of the normal human brain, heart function, and support drug development. It is used heavily in the imaging of tumors and the search for metastases within the field of clinical oncology, and for the clinical diagnosis of certain diffuse brain diseases such as those causing various types of dementias. PET is both a medical and research tool used in pre-clinical and clinical settings.
PET/CT-System with 16-slice CT the ceiling mounted device is an injection pump for CT contrast agent One of the disadvantages of a PET scanner is its high initial cost and ongoing operating costs. PET scan images can be reconstructed using a CT scan performed using one scanner during the same session. PET scanners can incorporate a CT scanner and are known as PET-CT scanners. These gamma rays are detected by gamma cameras to form a three-dimensional image, in a similar way that an X-ray image is captured. When the radiopharmaceutical undergoes beta plus decay, a positron is emitted, and when the positron collides with an ordinary electron, the two particles annihilate and gamma rays are emitted. A radiopharmaceutical - a radioisotope attached to a drug - is injected into the body as a tracer. PET is a common imaging technique, a medical scintillography technique used in nuclear medicine. Is widely used for detecting bone formation, and oxygen-15 is sometimes used to measure blood flow. FDG is commonly used to detect cancer, NaF 18 Different tracers are used for various imaging purposes, depending on the target process within the body. Positron emission tomography ( PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.
